noted.
1.5 Completed Two Sets of WF/PC-2 5091 (GTO High Latitude Parallel
Program: Cycle 4)

total of three seconds. No other anomalies were noted.
1.6 Completed FOS/RD 5588 (FOS Prism Snapshot Survey)
The Faint Object Spectrograph (Red Side) was used to make a Prism
observation of quasi-stellar objects NGC-4579 and MARK335 to study
their optical to ultraviolet continuum shapes. The observations were
executed as scheduled, and no anomalies were noted.
1.7 Completed FOS/RD/BL 5431 (FOS Observations of Liner Galaxy Nuclei:
Ultraviolet Clues)
The Faint Object Spectrograph (Both Red and Blue Sides) was used to
obtain ultraviolet spectra of the inner region of galaxy NGC-4579
looking for emission lines, stellar absorption lines, and continua.
The observations were executed as planned, and no anomalies were
noted.
1.8 Completed Three Sets of WF/PC-2 5369 (HST Medium-Deep Survey: Cycle
4 Medium, High Galactic Latitude)
The WF/PC-2 made a series of observations of high latitude objects
as part of a medium deep sky survey. The observations were taken in
parallel with other prime science observations. The observations
were completed as scheduled, and no anomalies were noted.
1.9 Completed WF/PC-2 5560 (WF/PC-2 Cycle 4 Calibration: Internal
Monitor. 1)
The WF/PC-2 was used to make several internal bias, K-Spot, and flat
calibration observations to monitor the CCD camera electronics, the
optical alignment, and to check for contamination. The observations
were completed as planned, and no anomalies were noted.
1.10 Completed Three Sets of WF/PC-2 5764 (WF/PC-2 Cycle 4 Calibration:
Internal Flats - Repeat)
The WF/PC-2 was used to make internal flat calibration images using
the VIS lamp and internal sources. The observations were executed as
scheduled, and no anomalies were noted.
1.11 Completed WF/PC-2 5397 (Determination of the Extragalactic Distance
Scale: Cycle 4 High)
The WF/PC-2 was used to make images of galaxy NGC-3351 to be used in
measuring the periods of Cepheid variable stars within the galaxy.
The observations were completed as planned, and no anomalies were
noted.
1.12 Completed WF/PC-2 5476 (Continuum Snapshots of 3CR Radio Galaxies)
The WF/PC-2 was used to make snapshot images of radio galaxy 3C220.2
as part of a continuum survey and to study the galaxy's morphology.
The observations were executed as scheduled, and no anomalies were
noted.
1.13 Completed Two Sets of FOS/RD 5391 (Mapping the Hydroxyl
Distribution in the Saturn Magnetosphere: Cycle 4)
The Faint Object Spectrograph (Red Side) was used to make
observations of regions near the planet Saturn (SATH2 and SATH3) to
study the distribution of hydroxyl radical (OH) in its
magnetosphere. Earlier investigations with HST have found the amount
of OH to be unexpectedly high. The observations were executed as
scheduled, and no anomalies were noted.
1.14 Completed Two Sets of WF/PC-2 5568 (WF/PC-2 Cycle 4 Calibration:
Decon)
The WF/PC-2 was used to make an internal flat field calibration
observation using the VIS lamp and the internal source as part of a
decontamination operation. Dark and K-Spot observations were also
taken. The observations were completed as planned, and no problems
were reported.
1.15 Completed WF/PC-2 5663 (WF/PC-2 Cycle 4: Photometric Calibration
Monitor: Fields Part 2)
The WF/PC-2 was used to make observations of globular cluster
NGC-5139 with various filters in order to check the photometric
calibration of the WF/PC-2. The observations were completed as

1.16 Completed GHRS/2 5421 (Abundances of Very Heavy Elements in the
Early Galaxy: Cycle 4 Medium)
The High Resolution Spectrograph (Side Two) was used to observe the
metal-poor halo star HD122563 to attempt to detect lines of the
heavy elements platinum, iridium, bismuth, and osmium. The
observations were completed as planned, and no anomalies were

Active Galaxies: Imaging)
The WF/PC-2 was used to make ultraviolet observations of the inner
regions of the low luminosity active galaxy NGC-5033. The objective
is to investigate the relationship between this object and higher
luminosity AGNs. The observations were completed as planned, and no
problems were reported.
1.18 Completed FGS 5135 (Extragalactic Astrometry and Astrophysics,
FT0-11,
Part 1 of Two)
The FGSs were used to make astrometric observations to obtain data
needed to measure the HIPPARCOS reference frame with respect to the
extragalactic reference frame. The observations were executed as
scheduled, and no anomalies were noted.
1.19 Completed Two Sets of WF/PC-2 5419 (A Search for Very
Low-Luminosity Active Galactic Nuclei in Nearby Galaxies)
The WF/PC-2 was used to make observations of galaxy NGC-4569, which

nuclei. The observations were completed as planned, and no problems
were reported.
